After upgrading to Logic X the USB midi doesn’t seem to work right with the Motif. I can see midi data coming into Logic but it is not passed to the output. This is only on port 1 of the 4 midi ports. The other 3 passes it through, but nothing triggers the Motif’s sound engine no matter what I do. Midi data are recorded into Logic - and if I connect the Motif via a midi cable to my Unitor midi interface - everything works. It seems to be the USB driver from Yamaha. I have the latest (1.9.9 I think).

I removed the 1.9.9 driver and installed 1.3.2 - and it’s the same deal. No Midi is passed through on Yamaha Port 1. It is, as before, passed through on port 2-4, but the Motif doesn’t respond to those ports. As before - I can record the midi data, and play back via the Midi Input, but USB=nothing

With the correct driver, this would seem to be a Logic setup issue. Port 1 is the XS tone generator, and should be the one that Logic sends MIDI data to for playing.

The Ports 1~3 are described on page 44 of the XS Owner’s Manual. Port 4 is used for communication by the Yamaha Editor.

I don’t use Logic. Hopefully someone who does will post with setup information concerning routing.
